Profile testing for epoxy substrates involves various methods like visual inspections based on ICRI CSP standards, depth gauge micrometers, replica tape profile assessments, surface roughness comparators, and digital surface profile analysis. These techniques ensure proper surface preparation, essential for a successful epoxy coating application.
Correct pH testing and understanding the pH scale are both vital for successful epoxy applications on concrete surfaces. Ideally, the pH level should be between 9 and 10 for efficient coating. Instruments such as pH meters or test strips can be used for accurate measurements. In industrial settings, concrete floors often face varying pH levels which can impact epoxy adhesion, hence regular testing is recommended. If pH levels are too high or low, neutralisation methods must be employed.
To ensure longevity in epoxy applications on concrete, appropriate pH measurements are vital. pH levels must lie between 6.5 and 9.9 for adhesives to be successful. Traditional test kits or digital meters can measure pH levels, with the latter offering precise results. In surfaces with high alkalinity, remediation steps are necessary before epoxy installation, and all testing outcomes should be recorded to maintain quality control standards.
Proper moisture certification is essential for epoxy flooring installations. Excess moisture in concrete can compromise its performance, causing issues such as lifting and bubbling of epoxy coatings. It is advised that concrete substrates' moisture content should stay below 3 pounds per 1000 sq. ft. Moisture testing is key to confirming substrate readiness and averting moisture-related failures, with several tools available. Contractors also need to adhere to professional certification standards for substrate moisture testing to prevent potential flooring failures.
